[PATCH] staging: rtl8723bs: simplify if-if to if-else

[Yihao Han]

Replace `if (!recvbuf->pskb)` with `else` for simplification and add curly
brackets according to the kernel coding style:

"Do not unnecessarily use braces where a single statement will do."

...

"This does not apply if only one branch of a conditional statement is
a single statement; in the latter case use braces in both branches"

Please refer to:
https://www.kernel.org/doc/html/v5.17-rc8/process/coding-style.html
